Experiment Investigation and Numerical Simulation of Snowdrift on a Typical Large-Span Retractable Roof

摘要: Retractable roofs are commonly used in designing large-span stadiums because of their versatility. However, retractable subject to sudden changes shape, and thus, factors addition those considered for conventional need be taken into account. In particular, considerably more sensitive snow loads shapes complex, snowdrift on may lead difficulties the operating roofs. To investigate distribution roofs, this study proposes a method based numerical simulation obtained using Euler–Euler multiphase flow theory. This model employs mixture by commercial computational fluid dynamics (CFD) software FLUENT. A suitable turbulence is selected through verification against two-dimensional (2D) data from field measurements reported previous studies. load cannot determined 2D easily. The accuracy predicting overall was verified experiments conducted horizontally roof. results show that nonuniform such distinct should considered.
